パイオニア往年の名機、A-006の故障品をベースに、徹底した点検・修理・内部リフレッシュを施した一台です。 本機は製造から40年以上が経過しており、多くの個体で接点不良やノイズが発生していますが、本品は信号系統の徹底的な分解整備により、当時のクリアで力強いサウンドが蘇っています。

【修理・整備・点検内容】

  • 信号系統の徹底洗浄(接点復活剤不使用)
    • メイン、バランス、TREBLE、BASSボリューム:完全分解清掃・整備済
    • フロントパネル全切替えスイッチ(電源除く):完全分解清掃・整備済
    • ※一時しのぎの復活剤は使用せず、物理的な洗浄と専用グリス(タミヤ製)で処置。接触不良による出音不良やガリは皆無です。
  • 基板部品のリフレッシュ
    • EQアンプ基板: 不良トランジスタ6個交換(2SA726⇒高信頼2SA992、他は同型番)。電解コンデンサー全13個をオーディオ用へ全交換済。
    • TONE基板: 全トランジスタ12個交換(2SA726⇒2SA992、2SC1919⇒2SC1845)。左右共に出力不可の状態から完治しています。
    • 調整用VR: EQ・パワーアンプ基板の半固定抵抗(計6個)を新品交換。バイアス・DCオフセットの調整を安定化させました。
    • フラットケーブル: RCA入出力~EQアンプ基板間の接続ケーブル(15芯)を劣化大のため新品へ交換。
    • はんだ割れ修正: 各基板の全箇所をチェックし、はんだ割れおよび予備軍を再はんだにて修正済。
  • 測定器による動作確認(オシロスコープ使用)
    • 正弦波入力(1KHz)にて左右出力バランス正常を確認。
    • 正弦波(10Hz~20kHz)入力にてBASS、TREBLE、各フィルターの変化を確認。
    • パワーアンプ及びEQアンプのBIAS、DCオフセット規定値調整済。
    • 内外部の徹底清掃。

【現在の動作状況】

  • 各入出力の正常動作を確認済(※MCカートリッジは手持ちがないため未確認ですが、切替時の音質・音量変化から正常と判断しております)。
  • ボリューム、スイッチ類の操作感はスムーズで、ガリや接触不良はありません。
  • 24時間以上のエージングを兼ねた安定稼働テストをクリアしています。
  • ※信号系統(スイッチ・ボリューム等)については、今回の整備により新品時に近い信頼性を取り戻しています。

【注意事項】

  • 外観は年代を考慮すると傷も少なく、主観ですが**「美品」**の部類に入ります。詳細は画像にてご確認ください。
  • 現在安定動作しておりますが、40年以上前のビンテージ品を修理したものです。長期の動作保証は致しかねますので、中古・修理品であることをご理解いただける方のみご入札ください。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
